Kindly note that as given in question | |||||||||
12 people were send an email by a friend | |||||||||
By Next day : | |||||||||
15 people received the letter and the number rises exponentially | |||||||||
Let us assume that the number of people receiving the letter is given by At | |||||||||
At | = | A0 * e^ kT | |||||||
A0 | = | 12 | (Number of people initially sent letter) | ||||||
k | = | Exponential growth rate | |||||||
T | = | Time period in number of days | |||||||
Also when T = 1 day | |||||||||
At | = | 15 | |||||||
=> | |||||||||
15 | = | 12*e^k | |||||||
1.25 | = | e^k | |||||||
Taking natural logarithm both sides | |||||||||
ln(1.25) | = | ln (e^k) | |||||||
0.223144 | = | k | |||||||
k | = | 0.223144 | |||||||
Hence the growth factor for number of letter received is | |||||||||
= | 0.223144 | ||||||||
Solution | |||||||||
